Answer:
Explanation:
this graph show the decrease in velocity with time
at time t=0 velocity is 40 m/sec
at time t=12sec velocity is decreases from 40 to 10 m/s
so the acceleration of the object at time=12 sec is
a=v/t
a=Δv/t
Δv=v1-v2=40-10=30 m/s
a=30/12=2.5 m/s^2
-- "Weight" is the gravitational attraction between TWO objects.
-- Its 'strength' depends on the mass of BOTH masses.
If either mass changes, then the gravitational force between them changes.
-- Your 'weight' on Earth depends on your mass and the Earth's mass.
-- Your 'weight on the moon depends on your mass and the Moon's mass.
From the list of choices, the best one is "The Earth and moon have
different values for the acceleration due to gravity.", although that
doesn't really explain much.
The colour of the star and the brightness.
